To all whom t may concern.-

Be it known that we, JOHN COCCHI and FRIEDRICH AUGUST ZEITLER, bothresidents of Berlin, Germany, have invented an Improved MechanicalAttachment for Musical Instruments, (for which we have obtained thefollowing patents: in Germany, No. 51,235,- dated August 6, 1889, andNo.'55,710, dated January 23, 1890; in England, No. 5,862, dated roApril 17, 1890, and in Spain, No. 10,872, dated May 31, 1890,) of whichthe following is a specification.

This invention relates to an attachment for musical instruments-such aspianos, harmoniums, bc-by means of which a perforated music-sheet ismade to operate the keys and produce thesound. -Themusic-sheetbymeans ofsuitable lever connections operates upon a set .of bellows that byexpanding or conzo tracting in turn operate upon the keys,and

consequently upon the hammers.

Our attachment is such that it may be applied to the existingconstruction of musical instruments without requiring alterations of 2 5the actions. l l a In upright pianos and similar Instruments where theattachment is placed under the keyboard it may be made entirelyremovable.

In the accompanying drawings, Figure 1 is 3o a vertical longitudinalsection of an upright piano provided with our improvement; Fig. 2, avertical transverse section with the lidA raised; Fig. 3, a longitudinalsection of the piano; Fig. 4, a vertical transverse section with the lidA lowered; F1gs.5 and 6, sectional, side, and end Views of the mechanismoperated by the music-sheet, showing lever F engaging a'perforation ofsuch sheet.

Figs. 32 and 33 are detailsofthe valve b3, 7o showing it, respectively, closed and open; and Fig.34 is a section on line P3 P3, Fig. 32.

The letter A represents a lid beneath the key-board B and turning ontrunnions d, journaled in the frame of the instrument. This lid carrieson its face the leversaa,op erated by the bellows, and the lever F,acted upon by the perforated music-sheet and the note-leaf motor E. Atits back the lid carries the bellows D D', with the posts GH,and the 8obellows J K and connecting-ports e, Fig. 4. The levers a a', which areoperated by the bellows, in turn operate the keys L Lof the piano byIneans of intermediate levers b, Fig.

2. These levers are pivoted to a rail g, and

at one end are adapted to be engaged by the levers a, while at the otherend they operate pull-d0wns 7L, that in turn act upon the keys. Thebellows D D levers a a', and levers b extend horizontally from side toside of the 9o piano-case beneath the'keys, as will be readilyunderstood. The levers F, however, to` gether with the music-leaf feedE, extends from the front to the rear of the instrument, Fig. 2.

When the mechanism is to be put into action, the lidA is swung into itshorizontal position, in which it will be maintained by catches le,Fig. 1. These catches may be disengaged (when the lid is to be swungdown) roo by means of a push-button l, acting upon pair of levers m o,connected by a rod n, and in turn acting upon the catches lo to spread aIn Fig. 22 the connection between the parts b q is shown to be made by ashort elbowlever t2, which replaces the disk t.v

Of course the mechanism above described may be readily reversed, so thatthe notes are not sounded by contraction, but by expansion of thebellows. As the surface of the lid A for the entire width of theinstrument may be utilized for the support of the sheet O, such sheetmay be made in the form of a band` or it may be made endlessorsectional. W'hen sectional sheets are employed, we prefer to connectthe sections by the joint shown in Figs. ll and 12. Here the sections O'O2 of the music-sheet are connected in such a manner that the inotion ofthe music-sheet will not have a tendency to injure the joint, but thatsuch motion will, ou the contrary, have the effect to bind the sectionsmore closely together. 'lo this etfect the sections O' O2 are connectedby strips P in the following manner: lhe strip P s placed below thejoint of sections O O2, and is then bent upwardly at both ends to passthrough such sections. The ends are then attened out upon the surface ofthe sections O' O2, both fiattened ends P' P2 extending in the directionof the motion of the sheet. Thus the ends will be kept out of contactand an even feed of the sheet maybe had.

What we claim is* l. The combination of a musical instrument with afolding lid A, a set of levers secured thereto and adapted to be engagedby a music-sheet, a set of bellows acted upon by the levers, and a setof litters operated. by the bellows and adapted to act upon the keys,substantially as specified.

2. The combination of bellows D D' with valve-rods o, operating both ofsaid valves, and a set of levers for operating thevalve-rods,substantiall y as specified.

3. The combination of bellows D D with ports G Il, valves M N, and withvalve-rods 1f,

having buttons tu, that are adapted to engage valves M, and leversadapted to operate the q', valves b2 b3, operated thereby, and thebellows D', substantially as specified.

7. The combination of bellows D D' with drawer Q', and the valves b2 b3and levers F', contained within such drawer, the drawer being adapted tobe partly or completely withdrawn, substantially as specified.

S. The combination of lever i with lifterf, lever f2, Valve V, andpedal-levers k' k2, substantially as specified.

9. The combination of music-sheet O, having perforation with levers F'c, rods q, disks t', litters f', levers f2, and pedal-levers k' k2,substantially as specified.

l0. The combination of a sectional musicsheet O O2, withconnecting-strip P, passing through the same and having its ends P P2upset on the same side of the music-sheet, so as to extend in the samedirection, substantially as specified.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
